Betula nigra

Black Birch

Betula nigra, or Black Birch, is a tall deciduous tree with a conical habit, known for its peeling bark that shifts from pinkish-orange to darker shades of brown and grey-white as it matures. Glossy green, diamond-shaped leaves bring freshness through summer before turning yellow in autumn. Its catkins appear in spring, adding seasonal charm, and many Irish gardeners choose it to bring structure and wildlife value to larger spaces.
